Ice on the Land Keywords
Fichas del conjunto (45)
- 1Morainesmall rocks carried and transported by a glacier
- 2Screepile of loose rocks - result of freeze-thaw weathering
- 3ProcessA series of actions with an end
- 4Abrasionwhen moraine carried by a glacier rubs against the ice and like sandpaper wears away sides and floor of valley (smooth surface)
- 5Freeze-thaw weatheringconstant freezing and expansion of cracks on mountains which fill with rainwater
- 6Pluckingwhen rocks on bedrock stick to the ice and get transported when the glacier moves away (jagged surface)
- 7Erosionrock being worn away due to the weather and animals/plants
- 8Weatheringthe breaking down of rocks by wind, rivers, sea & ice
- 9Transportationthe moving of rocks by wind, rivers,sea and ice (conveyor belt)
- 10Depositionputting down rocks by wind, rivers, sea & ice
- 11Rotational slipmovement of glacier along a curve
- 12Landforma natural feature of the earth
- 13Freeze-thaw weatheringWhen water gets into rocks cracks and freezes when temperatures go below 0°C. The ice expands and the cracks wide n so pieces of rock eventually break off.
- 14Corriedeep armchair-shaped crater on a hillside (often with tarn)
- 15Aretea knife-edged ridge often formed between two corries
- 16Pyramidal peaka sharp-edge mountain peak (formed between three corries)
- 17Truncated spuran eroded interlocking spur characterised by a cliff-like feature
- 18Glacial trough/U shaped valleya wide steep-sided valley floor eroded by a glacier
- 19Ribbon lakelong narrow lake on a glacial trough
- 20Tarna lake in a corrie
- 21Hanging valleya tributary glacial trough perched up on the side of a main valley (often marked by a waterfall)
- 22Boulder clay/tilltype of glacial deposit where very small particles (clay) are mixed with larger ones (boulders)
- 23Drumlinsmall hill of moraine, thought to be shaped by a second glacier moving over it after original glacier that deposited it retreated
- 24Glacier icecompacted snow after 100s of years
- 25Sublimationsnow turn directly to water vapour
- 26Snoutend of glacier
- 27Firnsnow that has survived a summer
- 28Avalancherapid and large fall of snow and rock down a cliff
- 29Accumulationsnowfall and avalanche
- 30Ablationsnowmelt, calving, sublimation
- 31Seracblock of ice
- 32Glacier budgetbalance between inputs & outputs
- 33Equilibrium linepoint on a glacier
- 34System analysisinputs, stores, outputs
- 35Calvingformation of icebergs
- 36Glacier retreatwhen ablation is greater than accumulation
- 37Glacier advancewhen accumulation is greater than advance
- 38Crevassegiant crack in glacier's surface
- 39Quaternary - Pleistocenethe geological period between 2 million and 10 000 years ago
- 40Interglaciala period of ice retreated associated with rising temperatures
- 41Glaciera river of ice usually extending downhill from an ice cap and occupying a valley
- 42Ice agea period when there are many glacial periods in a sequence quite close together. A time when ice sheets are found on continents.
- 43Ice sheeta huge mass of ice over 50 000 km² in size
- 44Glacial perioda period of ice advance associated with falling temperatures
- 45Ice capa smaller body of ice usually found in mountainous regions
